In the accompanying drawings the numeral 1 designates the oil cup. This oil cup 1 is preferably cylindrical in form and has its lower portion cone-shaped as indicated by the numeral 2 and is provided with a reduced outlet spout 3. This spout 3 is provided with threads by which it may be readily secured to the bearing to be lubricated. The upper end of the cup 1 is also provided with exterior threads adapted for the reception of the threaded side portion of a cap or closure 4:. The upper portion of the cup 1 is provided with diametrically oppositely slit or cut away portions 5 adapted for the reception of suitable bearings 6. These bearings. 6 are adapted for the reception of a crank shaft 7, and the bearings are retained securely in position by the flanged sides of the closure 4. The shaft 7 is provided with a centrally arranged offset 8, and pivotally connected with this ofiset is a plunger rod 9 having a plunger 10 adapted to normally overlie the outlet spout 3 of the cup.

form a bearing arm adapted for engagement with an operating rod 11. This operating rod 11 is adapted to be attached to the crank pin of an engine or machine so as to impart a reciprocatory movement to the plunger 10, which will force a portion of the lubricant within the receptacle 1 through the spout 3 and upon the bearing to which the cup 1 is attached.

It is to be understood that this oil cup is intended for use in connection with lubricants such as heavy oil which will not readily flow and which requires to be forced to the bearing or other machine element, and it will be noted that the device is extremely and that it will accom lish the purposes for which it is intended ciently and with certainty.
